Technology
Viable Direct Air Capture has arrived
The electrolyzer of the future.
Cheap materials.
Intermittent operation.
Producing CO₂ and H₂ at scale.
Brineworks’ electrolyzer is turning ultra low-cost DAC from dream to a reality. Most DAC systems rely on expensive sorbents, continuous operation, and thermal inputs. We use saltwater, intermittent electricity and zero precious metals for radically lower CAPEX and more flexible location options.
Step 1Electrolysis
Our system produces acid and base from saline water. The base is used for CO₂, capture and release.
Step 2Air Contacting
Air contacting with the base from our system is used to capture CO₂, into water.
Step 3Gas Production
Acid from our system is used to liberate CO₂, from the water which we capture for storage or utilization, all while co-producing H₂.
What we're building
CAPEX
Low - abundant metals, plastics, cheap membranes
High - platinum & expensive membranes
H₂
Maximized H₂ co-production (optional)
Low to none
Deployability
Anywhere - designed for solar PV without batteries
Where energy access is safe and stable
Energy price/cost
Solar + wind only = low cost
High base energy/battery prices = high cost
Intermittency ready
We don’t store energy. We don’t need to. Our system turns on and off with the sun — no batteries, no added costs.
Cost trajectory
Target: <$200/ton-CO₂ by 2030 Long-term: <$100/ton-CO₂
Deployment flexibility
Operates wherever low-cost renewable energy is available—from sunny regions and windy coastlines to hydro-rich northern areas.
